I found I had a flat on the rear inside dual, probably flat for some time as I rarely check. Could not notice visually, and unloaded ride was normal. I put 60 psi in it and noticed some sidewall expansion issue, so I knew it was shot. I left it in my bed under the tonneau cover and it blew today. I'm glad I was not around when it did as it really damaged my tonneau, it's heavy aluminum frame, and two clamps. I'm also glad I was not hauling the TC with the tire on the front axle. I don't think I would ever air these commercial tires down for the beach.

That's the first problem I've heard with an XPS tire.
I'm curious as to manufacturer date and tread condition.
Suggest you get the lot number and send an email or call customer to Michelin as they are probably interested in it and may want to make sure they get the core back for analysis.

My first response is 
That's what I have on the front of my truck right now.
As kohldad stated this happening is rare with XPS tires. Even more surprising is that it happened under no load while sitting under the canopy.
The XPS tires have steel wall in them. That's quite a rent to have ripped through the steel wall so I really wonder what happened to the tire.

My guess is that tire got driven for quite a lot of miles with next to nothing as far as air pressure in it.

This is a big surprise to me. I used XPS traction for years and have recommended them to others. Never a problem with them. I guess any product can have a failure, no matter how rare.
BTW, this is an opportunity to mention a good blowout safety video that has been posted on RV Net before. http://www.youtube.com/watch?v=lkwOE1yKY5c

Curiously, I saw a Kumho passenger tire with the exact failure today. I put new tires on the Mommy van and a tire failure came in the shop. The Kumho also blew standing still. About a cup of crumbled rubber inside the tire, but not typical damage on the inner sidewall from running low or flat. It wasn't run flat, but had been a problem child for not balancing well.

I had my 6 XPS's installed by Costco in 6/03, so I'm out the luck on their 5 yr road hazard warranty  I have about 75K on them now. I think riding with the tire at zero psi really caused the problem. Even though it did not take any load, I think constantly spinning a tire at 60+ mph empty could have damaged the sidewall belts ?

Either running it flat, or a manufacturing defect that made it past quality control, is what caused the blowout.
You said the sidewall looked funny when you pumped it up... I would've let the air outta the tire at that point, instead of letting it blow the tonneau off my truck  Hindsight is always 20/20...
